- COMBINED COIJTER- A l TD QJ I'NTER.

To all whom it may) concern:

'Be it known that I,

This invention relates to a combined colter and )01nter for plOWS, -2111(l;;l3ll 3-lIlVGIllllOIl consists in an mproved manner of 'mountlng thejointer on the colter "support-to enable the jointerto be adjusted and .firmly held in various difierent positions relative to the colter to meet thevarying conditions encoun-i tered inthe use of the-'devicein the field, the invention being applicable .to walking or riding plows either single oregangs; I

The memberlS is curved or rounded so as to conform to the rounded face of the supportingfinger 15,.

supporting finger, also horizontally in a fore and aft directlon, and also about a horizontal transverse axis and a vertical axis, as will be more fully descr1bed hereinafter. The

I jointer blade is seated at its rear side against the forward face of the memberlii of the frog and firmly secured thereto in any suit-' able manner, as by the fastening'bolts It will be observed from the vforegoing construction that due to the manner of supporting the jointer by the j ointer supporting arm through the medium of the frog 18 adjustably connected with the arm,which latter is in turn adjustably' connected with the colter supporting yoke, all of the various adjustments of the jointer blade relative to the colter such as are required in'the practical operation of the device in the field may be effected. For'instance by loosening the fastening bolts 13 which forward .end of the colter "supporting arm in the socket 12, the said arm may be adjusted within the socket hori zontally in a fore and aft direction which will, correspondingly adjust the jointer blade to or from the axis of the colter; and byturning the'colter supporting arm 11 in the socket about the longitudinal axis of the arm, the jointer blade may be set indifferent positions to and from the face of the colter and be caused to] assume difi'erent inclinations with respect to. the vertical plane of the colter. By firstloosening the fastening bolts 19, the jointer blade may be adjusted vertically with reference to the, colter by shifting the'bolts in, the vertical slots in the supporting finger l5; and by shifting the member 18 of the frog horizontally on the rounded face of the supporting finger, the jointer blade may be adjusted to different positions to and from the face of the colter as shown by the arrow in Fig. 5, the jointer blade in this adjustmentmoving around a vertical axis about the center of the are or curvature of the rounded face of the sup porting finger. Also the jointer blade may be tipped about ahorizontal aXis to vary its inclination with respect to the vertical by shifting the member 18" of the frog on-the rounded face of'the finger 15 so as'to carry the upper horizontal slot in the member 18" in. one direction and the lower horizontal slot in the opposite direction relatively to the bolts.

. The'jointer blade is therefore capable of I adj ustmentuniversally and in all directions with respect to the colter, and it may be held m its various adjustments rigidly and firmly construction there'is no liability of the'collection bythe growth;

The colter and jointer, combined as described, constitutes in effect a unitary structure, and after the jointer has been conparts of trash or vegetable nected with the colter and given its proper set and position relative to the same in the shops, the combined device may be applied as usual to the plow beam in'pro'per relation to the plow without requiring any further adjustment or fixing of the jointer. lVhilel have shown the colter in the form of a rotary colter disk, it will be manifest that the inventionfis applicable as well to a colter-of the well known blade form.

lnthe foregoing description and accompanying drawings I have'disclosed my invention in the particular form and detailed construction which I prefer to adopt but it will beunderstood that these details may be variously changed and modified without departing from the limits of my invention.

Further it will be understood that the invention is not limited to any particular form or construction of the parts except in so far as such limitations are specified in the claims.

In a combined colter and jointer, the combination of a colter support, a colter mounted thereon, a jointer-supporting arm mounted on the colter support provided on its rear end With a supporting portion having a rounded seat at one side, a j ointer frog having a fore and aft extending arm rounded to conform to said seat, releasable means extending through said frog and-arm and seat for holding the frog in different positionscn the seat, and a jointer applied to the frog.

6. In a combined colter and jointer, the combination of a colter support, a colter mounted thereon, a jointer-supporting arm mounted on the colter support and provided on its rear end With a supporting portion having parallel slots therein, a colter frog seated against said supporting portion of the arm and having parallel slots arranged at right angles to those in the supporting arm, fastening bolts extending through the slots in the frog and arm to secure said parts adjustably in fixed relations, and a jointer applied to said frog.

7. In a combined colter and jointer, the combination of a colter support, a colter mounted thereon, a jointer-supporting arm mounted on the colter support and provided at its rear end With a rounded depending supporting finger, having vertical slots therethrough, a colter frog provided With a rounded surface applied to the finger and having horizontal slots therein adapted to register with the slots in the finger, fastening bolts extending through said registering slots to secure the parts adjustably in fixed relations, and a j ointer applied to said frog.

8. In a combined colter and jointer, the combination of a colter support, a colter mounted thereon, a j ointer adapted to cooperate with the colter in trimming the corner of the furrow slice, and connections between the j ointer and colter support to sustain the jointer in position, said connections being constructed to admit of the adjustment of the j ointer relatively to the colter, vertically,
